IMPROVEMENT lN BUTTER-PAILS, &c.

The Schedule referred to ln these Letters Patent and making part of thesame.

To all whom fit may concern.'

Be it known that I, Ancora ROBERTSON, of East Rupert, in the county ofBennington and State of Vermont, have invented certain new and usefulImprovements in Packing Pails for Butter, 85o.; andI do hereby declarethat thefollowing is a full, clear, and exact description thereof,reference being had to the accompanying drawing making part of thisspecification and to the letters of reference marked thereon, likeletters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

My invention relates to vessels or packages. for containing butter,lard, and'similar articles; and

The invention consists in providing the Vessel with a cover that willvclose it air-tight, and that can be attached and detached at will, ashereinafter more fully explained.

Figure 1,l is a transverse vertical sectionwith the cover on.A

Figure 2 is a top plan view with a portioulof the cover broken away. v

' Figure 3 is a vertical section of a portion with the cover removed.

1n constructing my device I make the body A in the style of an ordinarywooden pail or bucket, with a bail for convenience in handling it.

Near .the top I cut a groove, in which I secure an annular rim or top,B.

1n the inner edge of this topB I out two notches, o, directly oppositeeach other, as represented in tig. 2, and on the under face of the top Ibevel it from these notches o Varound for some distance, as representedat n, iig. 3, and as indicated by dott-edlines in ig.-2.

I then providea cover, O, somewhat greater in diameter than the openingin the top B, with a` portion of its lower-part turned oii so as to titinto the opening, as represented in fig. l.

i Across the under side of this cover C II secure a rod, c, with' itsends protruding slightly beyond its under face, as shown in figs. 1 and2.

Across its top` I secure a cleat, b, which serves to keep the cover fromwarping, and also to turn it by, and to handle it in applying it to orremoving it from the vessel.

I also provide a packing-ring, e, of proper size to fit under the flangeof the cover and between it and the top B, as shown in figs. 1 and 2.This ring may be made of sheet-rubber, or of cloth saturated withpar-affine; the latter being preferable for butter on account of itsinodorous qualities, and therefore less liketightnpon the packing andthus eiiectually close the vessel.

To remove the cover it is simply turned back until the ends of rode areopposite the notches o, when it can be at once lifted off.

By these means I produce a package in which butter, lard, and similarproducts can be preserved and transported in the most effectual manner.

Having thus described my invention,

What I claim is- 'An improved package for butter and similar articles,consisting of the vessel A having the annular top B, provided with thenotches o and inclines n, and the cover C provided with the rod c, allconstructed and arranged to operate as herein set forth.
